Title: Improvements in or relating to apparatus for assembling electric components with axially extending wire lead-outs
Inventor: AMELCHENKO ALEXEI SEMENOVICH
IPC: H01C17/28
Filed: 1969-08-27
Abstract: 1,255,868. Making electrical components; assembling force fits. A. S. AMELCHENKO. 27 Aug., 1969, No. 42690/69. Headings B3A and B3U. Apparatus for assembling electric components having axially extending wire lead-outs comprises a feed mechanism 24 for feeding component bases 22 to punches 41 for pressing caps 9 having wire lead outs 10 on to both ends ofeach base and a shaft 6 for actuating the punches. The feed mechanism comprises a movable carriage 32 provided with a plate 33, a spring-biased pawl 34 for locking a base 22 to the plate 33 and a lever 27 resiliently coupled to the shaft 6. A motor 1 drives the shaft 6 via a clutch 5 and while it is running, hoppers 8 are vibrated to deliver the caps 9 to feed means 11. The bases 22 are delivered from a hopper 21, which is actuated by a motor 20. Cams 40 reciprocate carriages 39, which by means of levers 18 and leaf-springs 19 reciprocate the feed means 11 to deliver the caps 9 through guides 12 to catchers 13, 14, into which fall the lead-outs 10. As the punches 41 move towards each other, the leadouts 10 enter openings (46) therein, passing into passages (47), Fig. 2 (not shown) and the caps 9 abut limiters 43. Simultaneously, the carriage 32 is driven by a cam 25 and spring-loaded levers 26, 27 to deliver a base 22 to the assembly station. As the punches 41 approach the catchers 13, 14, a cam 16 pivots levers 49, 50 about a shaft 51 to release the lead-outs 10 from the catchers. The caps 9 then enter the opening- ings (46), the limiters 43 are withdrawn and the caps forced on to the ends of the base 22. The carriage 32 is then returned by the cam 25 and its associated levers 26, 27, while the pawl 34 releases the base 22. When the levers 49, 50 are fully deflected, springs (55), (57) re-set the catchers 13, 14 to their initial position, Fig. 5 (not shown). During the return movement of the carriages 39 the feed means 11 are actuated to deliver the next pair of caps 9 to the guides 12. Pushers 60, which are mounted in the punches 41, strip the lead-outs 10 of the assembled resistor from the punches 41 as they are withdrawn. The resistor falls on to a separator (58), which places satisfactory and faulty resistors in respective containers, Fig. 5.

Title: Improvements in or relating to a linear motion clutch for punch presses
Inventor: SCHOTT ARTHUR KENNEDY
IPC: B30B1/26
Filed: 1960-12-13
Abstract: 890,250. Hydraulic apparatus. HOUDAILLE INDUSTRIES Inc. Dec. 13, 1960, No. 42871/60. Class 69 (2). [Also in Group XXII] A clutch for a punch or nibbling press comprises a hollow piston 17 in a reciprocable cupshaped cylinder 22, chambers 26, 27 in the piston and cylinder for containing a fluid 28, and an arrangement 40 which is disposed within the cup-shaped cylinder and carried thereby and is movable to positions to effect driving and non-driving engagement between the cylinder and piston through the fluid. The piston is connected by a pin 16 to a pitman 14 on an eccentric formed on a rotatable shaft 12 and is formed with a valve seat 30 engageable by a valve plate 40 secured to a pin 48 axially movable in a member 55 connected to the closedend of the cylinder which carries a tool 25, the pin 48 and member 55 providing a lost-motion connection between the valve plate and cylinder. An armature 43 is secured to the valve plate and co-operates with a solenoid 41 which is carried by the piston and operated by hand and footoperated switches and by limit switches actuated by a cam rotated by the shaft 12. When the solenoid is de-energized, the fluid is free to flow between both chambers 26, 27 so that the movement of the piston is not transmitted to the cylinder. Energization of the solenoid as the piston moves upwardly causes the valve plate to engage the valve plate but, as the piston approaches its uppermost position, the head 52 of the pin engages a surface 60 on the member 55 to prevent further upward movement of the valve plate so that fluid from chamber 27 can flow into chamber 26. On the downward movement of the piston, the seat 30 re-engages the valve plate to prevent flow of fluid between the chambers so that the motion of the piston is transmitted to the cylinder which moves in a housing 20 against the pressure of springs 36. The limit switches actuate relays in a circuit which permits single or continuous reciprocation of the cylinder. During continuous reciprocation, the opening of the valve at the uppermost positions of the piston enables loss of fluid from the chamber 26 to be replenished by flow of fluid from chamber 27. Specification 727.087 is referred to.

[Also in Division G1] A circuit for detecting such faults as distort the waveform of an electrical supply, comprises filters 5, 6 connected to receive a supply signal and to transmit the fundamental and harmonic components respectively to a comparator 7 which provides an output dependent on the relative values of the components. As shown, the comparator 7 comprises two transistor amplifiers T1, T2 arranged in a balanced configuration. The fundamental component is applied through a current transformer CT1 and a rectifier BR1 to the base of the transistor T1 and the harmonic components are applied through a current transformer CT2 and a rectifier BR2 to the base of the transistor T2. The voltage produced across a resistor R3 is indicative of the ratio between the fundamental and harmonic components and is applied to a level detector (not shown). An alarm or control circuit is connected to the level detector. If the supply signal is a current signal it may be applied through a transactor 4 and a thyrector 14, but if this signal is a voltage signal it is derived from a voltage transformer. A time delay circuit may be connected between the level detector and the circuit 12. The circuit may be used to protect against earth faults due to fallen conductors, arcing faults on insulation and earth faults on domestic appliances. It may be used in testing electric cables and capacitors.

Filed: 1972-09-25
Abstract: 1400477 Selective signalling NORTHERN ILLINOIS GAS CO 25 Sept 1972 [15 Dec 1971] 44200/72 Heading G4H In a read-out system, a control unit can select one of a plurality of remote units by means of coded signals sent over an electrical power supply line, the selected remote unit responding by sensing readout data over the supply line to the control unit. As disclosed, the coded selection signal consists of two BCD digits and is followed by eight "ones", and all are sent by frequency-modulating a carrier. At each remote unit, the signals are demodulated, filtered and used to derive clock signals which shift the two BCD digits into a shift register, and if they are recognized by a code comparator, the encoded output of an indicating device (utility meter or copy counter of a copying machine) is inserted into the shift register and shifted out by the clock signals derived from the eight "ones", to be transmitted to the control unit by frequency-modulating a (different) carrier. Operation is duplex. Simplex operation is possible instead. In another embodiment, there are a plurality of control units with respective groups of remote units, e.g. one control unit per building, and a central station, which may be mobile, supplies the selection signals to the control units and receives the readout signals from them, either by radio or using multi-frequency tones over telephone lines.
